2 Claims.

The subject-matter of the present invention relates generally to the artof collection and separation of materials, but more specifically has todo with a device for the arresting and collection of foreign materialspresent in the cooling fluid of the circulatory system of an internalcombustion engine, or the like.

Primarily, the object of the invention is to provide a device of theabove-mentioned character which may be conveniently installed betweenthe outlet pipe of the water jacket of an internal combustion engine, orthe like, and the inlet in the tank at the top of a radiator, withoutmaterially altering the present constructions.

Another object is to provide a device adapted to receive and house atrap element suitably constructed to receive foreign materials arrestedby a screen borne by the upper end of said element.

A still further object is to provide means serving as a guide wherebysaid trap element and its screen element may be positively arranged in apredetermined position within the tubular portion of the device.

Still another aim of the invention is to produce a device that may beattached to the tank of a radiator by difierent ways and methods.

Other objects and advantages will ,be apparent as the nature of theinvention is better set forth, and it will be understood that changeswithin the scope of the claims may be resorted to without departing fromthe spirit of the invention.

In the drawings:

Figure 1 is an elevation illustrating one method of connecting myinvention to the cooling system of an internal combustion engine.

Fig. 2 is a central longitudinal sectional View of the device. i

Fig. 3 is an elevation of the trap element removed from the device.

Fig. 4 is a view similar to Fig. 2, but slightly reduced in scale, andshowing the casing portionof the device.

Fig. 5 is a fragmentary elevation of the lower end of the tubularextension of the device and showing a closure applied to the extremitythereof and means for holding said closure in position.

Fig. 6 is an inverted plan view of said tubular extension with theclosure removed.

Fig. '7 is a central longitudinal sectional view of another form of thedevice.

Fig. 8 is a. bottom plan view thereof.

Fig. 9 is an inverted plan view of the lower end of the tubular portionshown in Fig. '7.

Fig. 10 is an elevation of the trap element 'shown in connection withFig. 7.

Figs. 11, 12 and 13 show difierent methods of attaching the device tothe upper tank of a radi- 1 ator.

jacket ll of an internal combustion engine, re-

spectively. Said casing also includes a tubular extension l2 disposedangularly with respect to the longitudinal axis of said tubularportions, as shown in Fig. 2, and being adapted to receive 15 a trapmember I3 having a bottom 44, the wall of said member being cut away topresent an opening [5 which aligns with the passageway in said tubularend portions 6 and I when the parts are assembled as in Fig. 2. Uponinspection of Figs. 2 and 3 it will. be noted that the upper end of saidmember I3 is cut on the bias to support a screen I6. As shown in Fig. 1the end portion 6 is coupled to the inlet pipe 8 by means of suitablerubber tubing ll, whilst he end portion 1 is joined to the outlet pipeI!) by means of rubber tubing l8, suitable clamping members l9 and 20being resorted to. The casing is preferably made of rust-proof materialand in view of the opening IS in said trap element I3 the circulatingcooling medium has a clear passage through the tubular portions 6 and I,said screen I6 interrupting and arresting foreign substances in saidcooling medium and preventing the passage thereof to said radiator, thuspreventing clogging, or the like. As shown in Fig. 2 said screen It isinclined at an acute angle to the transverse plane of said tubularportion and in this position it provides for the deposit of foreignsubstances and their subsequent descent into said trap member l3, saidmember having a bottom I4 for retaining said substances.

In assembling the device for use, the trap member I3 is pushed upwardlyinto said extension l2 and to assure that the screen It is properlypositioned within the casing, the Wall of said extension is providedwith a rib-like formation 2| which cooperates with grooves 22 in saidtrap member l3, in an obvious manner. The bottom M of said member I 3 isprovided with a handle 23 which facilitates the entry and removal ofsaid trap member and the latter isim'ally in the position indicated inFig. 2 by means of-a cap 24 and a washer 25. Said cap 24 may be threadedthe bight portion 3| of said ball engaging the abutment 32 to assure atight fit. When the bail is swung to the position indicated by dottedlines in Fig. 5, the cap may be removed. To properly mount the trapmember with its screen at the necessary position, I propose to provideslots 33 which receive the side portions of the handle-like element 34,as shown in Fig. 6. The trap member will also be provided with a certainmarking, as indicated at 35 in Fig. 3, to assure that the screen will beproperly positioned.

When the usual symptoms of a clogged strainer or screen make themselvesapparent, the cap 26, or the cap 21, may be removed and the trap element13 can be drawn out of the extension l2 for cleaning so that allmaterials in said member and all foreign matter clogging said screen'areremoved and the trap member replaced for further service.

In Fig. 7 the casing 36 is provided with end portions 31 and 38,theformer portion being provided with a flange 39 which is suitablyriveted .said end portion 31 is provided with threads 41 to engage athreaded nipple 48 suitably fastened to said tank 40. Reverting to Fig.'1 it will be noted the tubular extension 48 extends downwardly fromsaid casing 36 and receives the trap element 49, having a bottom 50, theupper end being cut on the bias and carrying a screen 5| disposed in thepassageway of said casing 36. The rear of said element 49 is cut away at52 so the cooling medium may flow uninterruptedly through saidpassageway. Said screen 51 arrests the passage of foreign substances insaid cooling medium which drop into the trap element 49 for subsequentremoval. In order to properly position said trap element in theextension 48, the latter is provided with diametrically opposed slots53, see Fig. 9, to receive the ends of the -handle-like element 54carried by the bottom 58 and the cap 51 is secured in position by meansof the bail 58 pivotally carried by said extension a,os4,242

'48, asshown. The bight portion of said bail is snapped over theabutment 59 in the same manner as pointed out hereinbeiore. I! desired,the end of said extension 48 may be threaded to engage a threaded cap 01the type shown in Fig. 2.

The use of the device assures that the cooling medium will circulate ina satisfactory manner and that all foreign. substances will berestrained from entering the top tank oi a radiator and the tubesthereof, thus preventing overheating of the engine or an impairment tothe satisfactory operation of the cooling system.

I claim:

1. A filtering device for use in conjunction with the cooling system ofan internal combustion engine, or the like, said device comprising acasing embodying a tubular portion, the ends thereof adapted forconnection with the inlet of a radiator and the outlet of the waterjacket 0! an engine, said casing also including a tubular extensiondisposed angularly with respect to said tubular portion, said extensionhaving a rib-like formation extending inwardly from the wall thereof andlongitudinally of said extension, a removable trap member positionedwithin said extension, and having a bottom, the wall of said memberbeing cut away to present an opening registering with the passageway insaid tubular portion to permit the course of the cooling liquid therethrough, said trap member having its side wall grooved to register withthe rib of said extension to assure a predetermined positioning of saidtrap member within saidcasing, and a screen borne by the upper end ofsaid trap member and spanning said passageway to arrest the travel oi.foreign material therethrough.
